Israeli student Levi Rosenblatt, who was stabbed by an emotionally unstable Long Island man inside a Brooklyn synagogue, remained in stable but serious condition at Bellevue Hospital Center on Wednesday night.

Rosenblatt was stabbed on the left side of the head and neck by Calvin Peters, 49, who walked inside the Crown Heights synagogue at 770 Eastern Pkwy. after midnight Tuesday. According to witnesses and police, Peters blurted out "I am going to kill you" and anti-Jewish remarks.

Officers opened fire on Peters after he attacked Rosenblatt and lunged at an NYPD officer, police said.

Rosenblatt, 22, is a student at the Chabad-Lubavitch Hasidic Movement. His parents arrived from Israel on Wednesday to be at his beside. Six Israeli soldiers in New York City on behalf of the Chabad Israel Center in Manhattan also visited him.

"We wanted to show him our support and warm his heart," said Chabad Israel Center's rabbi, Uriel Vigler. "We are very familiar with terror and we want to show him our support and solidarity."

The soldiers could not see Rosenblatt, who was resting in his room, said Vigler. Instead, Vigler, two other rabbis and the soldiers held a prayer vigil outside the hospital for the student's quick recovery.

Rosenblatt, who lives in Israel, was studying about 1:40 a.m. inside the basement of the synagogue when Peters attacked him, police said.

NYPD Commissioner William Bratton said the stabbing did not appear to be terror-related. Bratton said that the shooting by officers looks to be "justified." He also said that the NYPD's hate crimes unit will investigate to determine whether Peters' attack was a bias incident.

Peters first entered the synagogue just after 5 p.m., police said. He left and returned at midnight but was escorted out. When Peters came back, he had a 9-inch knife with a 41/2-inch blade, police said.

At one point, Peters obeyed police commands to place the knife on a table. But Peters picked up the knife again and lunged toward an officer, police said.

Peters' family on Long Island told Newsday that Peters had bipolar disorder, but was a "loving father to two kids."
